"This company goes above and beyond! Very professional and honest. Matt replaced my AC and furnace and did a fantastic job. I will definitely be using them again for all my service and maintenance."

"We have used this company for both rental and owner-occupied properties. They replaced the roof, gutters, and worked with the company to make sure that our awnings and other items were replaced. They also worked very well with our insurance company and we had no problems at all. Jacob made everything so easy that if we ever need anything else done and they can do it, they have the job."

"Clint replaced steps on our deck. He was very efficient and they turned out great! Would definitely use him again!"

"I received 3 bids to replace the old HVAC system on the condo I purchased in September 2018. I was most satisfied with Missouri Furnace's bid, taking into account the price, the brand of new system (Trane), and the efficiency of the new unit. Also, as I live in a 4 story condo building, a crane was required to remove the old air conditioner and replace with the new unit. Once we had agreed on a price and the contract was signed, I was scheduled for installation the following week. I like that my new furnace has a 4 inch filter, so that I do not have to replace it every month, In May the weather was not so hot that immediate installation was required. I was extremely pleased with the promptness and professionalism of the team. The new HVAC system was installed quickly and with no drama. It is also working great. I will no doubt call on Missouri Furnace to check on my a/c next spring before the summer of 2020."

"The service was excellent! They arrived to pick up the vehicle a day earlier which was great. They delivered the vehicle right to my daughter's door and found a side street to unload. The service was delivered within the time frame given. All of my questions were answered via phone or email and the paperwork was seamless and the price was very reasonable."

"He went with me to get a replacement faucet and he gave me the guidelines and then just let me choose what I wanted to go with. He did a great job and I am very pleased."

"Excellent! Jason believes in quality as well as a good price. He's organized, reliable, knowledgeable & explains things well. He inspects everything, including proper ventilation prior to installation & again inspects the work in progress to ensure we have a roof that lasts. We were very impressed with his crew. They showed up on time, were polite & worked steadily like an organized assembly line. They finished the job in one day & cleaned up the site perfectly."
